Patented Sept. 1l, 1906.

Application filed January 16, 1906. Serial No. 296.297.

To all whom it may concern:

Be it known that GEORGE D. HOLBROOK, a citizen of the United States, residing at Seekonk, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Bracelets, of which the following is a specification.

This invention has reference to an improvement in bracelets, and more particularly to an improvement in concealed hinges for bracelets.

The object of my invention is to improve the construction of a concealed hinge for bracelets, whereby the construction of the hinge is simplified and the cost of manufacturing tlie same reduced.

My invention consists in the peculiar and novel construction of a' concealed hinge for bracelets, having details of construction as will be more fully set forth hereinafter.

Figure 1 is a side view of a bracelet provided with my improved concealed hinge and showing the bracelet in the closed position in full lines and in the open position in broken lines. Fig. 2 is an enlarged detail sectional view of the hinge end of the bracelet looking at the outside face of the hinge. Fig. 3 is an enlarged detail sectional view taken on line 3 3 of Fig. 2 and showing the hinge in the closed position. Fig. 4 is an enlarged detail sectional view similar to Fig. 3, showing the Fig. 5 is an enlarged detail view looking at the outer face of the solid hinge member, and Fig. 6 is an enlarged detail view looking at the outer face of the tubular hinge member.

In the drawings, ay indicates one semi-oval half, l) the opposite semi-oval half, and c the improved concealed hinge, of the bracelet.

The semi-oval halves a and t are constructed from a tube which is oval in cross-section. The half a has the open end a for the hinge c and the end c2. The half t has the open end t for the hinge c and the end b2. The ends a and b and the ends a2 and b2 coincide when the bracelet is closed. The ends a2 and b2 may be provided with any one of the wellknown forms of catches adapted to hold the ends together when the bracelet is closed.

My improved concealed hinge c consists of a solid member d and a tubular member e. These members d and e are curved to conform to the contour of the bracelet and shaped to fit in the open ends a and t of the bracelet. The member d is constructed to have a solid body portion d', from one end of which extends the side arms d2 d2, forming a central opening d3, and having the oppositely-disposed semicircular notches d* d4 in their outer edges, as shown in Fig. 5. The tubular member c is formed from thick sheet metal and shaped to have the tubular body e/ from the inner face of which at one end extends the central arm e2, merging into the T-shaped end e3, which forms the pintle of the hinge, as shown in Figs. 3 and The width of the arm c2 coincides with the width of the opening d3 in the member d, and it is curved outwardly to bring the T-shaped end into the notches d* d4, as shown in Figs. 2 and 3.

The hinge is assembled by placing the arm e2 of the member e in the opening d3 in the member d with the T-shaped end e3 in the notches d4 d", as shown in Fig. 2. The members d and e of the hinge are now forced into the open ends a and b of the bracelet into a position to bring Vthe end of the member e (adjacent the arm e2) inside the end t of the bracelet, thus forming a shallow recess c4 in the end b', and the T-shaped end e3 against the inner face of the outer portion of the end a of the bracelet, thereby locking the T- shaped end e3 in the notches d4 d4, as shown in Fig. 3. The body portions d and c of the hinge members are now secured in the ends a and b of the bracelet by solder or other means.

When the bracelet is opened, the member d of the hinge in the end a of the bracelet pivots on the T-shaped end c3 of the member c and the outer edge of the end a of the bracelet swings into the recess e4 and against the concavedface of the arm e2, as showninFig. 4.

By the use of my improved construction I provide a bracelet with a strong and durable concealed hinge having only two members, each of which is formed integral.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A concealed hinge-joint for bracelets, comprising two members each of integral formation, one embodying abody portion formed with'a pair of forwardly-proj ecting arms having a space between said arms throughout the entire area thereof, and with a notchon lOO edges, the second body portion being formed T-shaped arm on its outer end which merges into said second body portion at a point adjacent the bottom thereof, said curved arm extending upwardly in said space between said pairy of arms and having its T-shaped head extending in said arms.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
